Changing variable value with a rule

---

Hello,

I new with pimatic, and I would like to change a text variable with a rule.

For example, when $DHT11.temperature > 40 then set $Message.temp := “too hot”

I already created and initiated every variables needed, but I still have that “Could not find an provider that provides the next action” error. I don’t understand how to solve this issue.

Any idea? or script examples I could learn from ? Or tutorials about rules, scripts and variables ?

Thanks

@Roman-Legrand I think what you can do is something like

when $DHT11.temperature > 40 then set $messageText to “too hot”

In this example $messageText is a user-defined variable which can be added with the variables editor of the web frontend. I don’t think it is going to work with variables for device attributes like $Message.temp!

Try this:

When $dhttemp > 40 Then set $thevariable to "it is to hot"

Have you tried without the keyword set?
I think you can either use set $variable to "string" or $variable := "string"

Second guess would be you are trying to set the variable in the device directly and not the variable that is shown in the VariablesDevice.

"devices": [
  {
  "class": "VariablesDevice",
  "name": "Info",
  "id": "message",
  "variables": [
      "name": "temp",
      "expression": "$strMessageTemp"
    ]
  }
  ]

So $strMessageTemp := "too hot" should work, set $strMessageTemp to "too hot" also, but set $message.temp to "too hot" not.

If that doesnt work: did you create the variable as string?

"variables": [
  {
    "name": "strMessageTemp",
    "value": "",
    "type": "string"
  }
  ]

edit: seems, I typed too slow

Thank you ! That work now.

As you said, I wanted to change a variable in a device directly, which doesn’t work.
